Stable Isotope Labeling


Isotopic labeling is a technique used to track the passage of an isotope (variants of a particular chemical element that differ in neutron number) through a reaction, metabolic pathway, or cell. The nuclides used in isotopic labeling may be stable nuclides or radionuclides, which the former labeling is called stable isotope labeling. Stable isotope labeling can act as a tracers used to model several chemical and biochemical systems, because the chosen isotope can be identified through nuclear magnetic resonance (NMR) and mass spectrometry (MS). For example, the position of the isotopes in the products is measured to determine the sequence the isotopic atom followed in the reaction or the cell's metabolic pathway[1]. The labeled products can be obtained by replacing specific atoms with their isotope. Some of the most common stable isotopes are 2H, 13C, and 15N. There is a wide range of compounds that can be custom labeled with stable isotopes, including: NMR solvents, amino acids, nucleic acids, lipids, common metabolites and cell growth media, etc.
